well, you might be able to lower the IPL in the timer A handler?
Yep, you can do that. You must set sr back to $2300, and clear the ISR timer A bit (I think it is ISR), so even other low-priority MFP interrupts trigger. And use a mutex in your timer A interrupt to prevent itself from running if it is not finished.
This is what I did in the old doom dsp version with music (timer a). The routine was taking so long that ikbd interrupts (lower mfp priority) could not trigger, and moving the mouse was crashing the program.
